Common Security Vulnerabilities in Web Applications and Mitigation Strategies
Cross-Site Scripting (XSS)
XSS vulnerabilities occur when attackers inject malicious scripts into web pages. To mitigate XSS, developers should sanitize user input, use input validation, and implement secure coding practices.
SQL Injection
SQL Injection attacks involve inserting malicious SQL code into web forms or URLs. Mitigation strategies include using parameterized queries, input validation, and implementing least privilege principles.
Cross-Site Request Forgery (CSRF)
CSRF attacks trick users into unknowingly making requests on authenticated websites. Developers can prevent CSRF by using anti-CSRF tokens, implementing SameSite cookies, and validating referrer headers.
Clickjacking
Clickjacking involves hiding malicious elements on a web page to trick users into clicking them. To mitigate clickjacking, developers should use X-Frame-Options headers, implement frame-busting scripts, and avoid rendering sensitive content in iframes.
